How can I convert 1080 24p footage to 1080 30p or vice versa so I can edit with both in the same sequence?

Hi. I have some footage that is 1080 24p and some that is 1080 30p. My sequence setting right now is set to match the 24p footage. When I playback what I have on the timeline, the playback of all the 30p shots do not look like their playing smooth. Almost looks like the footage is kind of skipping. I know its because my sequence is currently set to match the 24p footage but I'm not sure if I need to convert the 30p footage to 24p or vice versa? How would I go about doing that and which one do I need to do? Your help would be greatly appreciated. Thank you.

You're 30fps footage is always going to look a bit choppy when playing it back on a 24fps timeline because it's going to be skipping frames or trying to blend them. It's never 100% perfect.

Well, I say that. There are ways around it but, depending on the style of footage, you can get pretty good results using a convertor with motion estimation or some kind of pixel flow calculation. In Compressor in the Frame Controls section (You may have to turn it on by clicking the little cog button) there is a group called Retiming Control . In that group change the Rate Conversion to 'Best (High Quality Motion Compensation)' and check the radio button that says 'so source frames play at ##.## fps'. The FPS are set in the Encoder settings.

Are you suggesting that I need to convert all of my 30p footage to 24p first, with compressor and then bring those shots back into my 24p sequence for the final export of the entire project?

Yes.
Or you can use Cinema Tools or AE.
Make a back up copy of footage first.

Absolutely. For FCP success, frame rates must match. You've probably heard the Apple marketing weasels say you can put different frame rates into the same timeline, but they never mention that it won't look good.

I agree. What i ended up doing was using Cinema tools to conform the 30p raw footage files to 23.98fps to match the other footage and sequence. Worked perfectly. Then I just went back and re adjusted the cuts of the 30p shots that were already on the timeline. The 30p footage that I converted played back smoothly. Also made a backup of all the original footage just incase things did not work out right using cinema tools to conform. Thanks for everyone help.
